Bug details

impossible to have high quality display with bitmaps

With cs6 no problem. The same bitmaps files (TIFF) with CC, the display is very bad, even in high performance. Impossible to find a solution with technical assistance. Graphic designers with whom i works have the same problem. Apparently on the forums it would be a known bug. I work with windows 10.
Two screenshot to see the difference between CS6 and CC
